Owing to light weight and excellent formability aluminum alloys and composite are widely used for automotive, aerospace and marine applications. In this study, multiple reinforcements namely, mica, Graphite, and e-glass fibers were utilized to synthesis Al7075 alloy-based composites. The hybrid composites with different content of reinforcements have been fabricated by the liquid metallurgy route. Both Al7075 alloy and hybrid composites have been studied for microstructure and corrosion behaviour. Corrosion characteristics of the alloy were analysed by the salt spray corrosion test as per ASTM standard. Microstructure reveals a fairly homogenous dispersion of hybrid reinforcements with good metallurgical bond with aluminum alloy. The impact of time durations ranging from twelve to ninety-six hours on weight reduction was studied. Weight loss decreases with increased hybrid reinforcement content. An increase in salt spray test duration enhances the fat reduction for each alloy and also hybrid composites. Under all of the circumstances studied hybrid composites demonstrate reduced weight loss when examined with unreinforced aluminum alloy.
